I have the same problem when I am using SMTP service to send emails.
With PHP is working fine.

I have found the issue. The problem is when it tries to send the email (class GDPR_email). The plugin uses the function get_do_not_reply_address (file includes/class-gdpr-email.php) to generate a noreply address:

private static function get_do_not_reply_address() {
	  $sitename = strtolower( $_SERVER['SERVER_NAME'] );
    if ( substr( $sitename, 0, 4 ) === 'www.' ) {
			$sitename = substr( $sitename, 4 );
    }
	  return apply_filters( 'gdpr_do_not_reply_address', 'noreply@' . $sitename );
	}

The problem is that I run wordpress with docker and the SERVER_NAME, for me, is wordpress. So the generated email is noreply@wordpress. But because this address does not exist it raises an error.

What I have done: I have added a filter to force the noreply address in my functions.php:

function my_gdpr_do_not_reply_address() {
   return 'contact@mysite.fr';
}

add_filter( 'gdpr_do_not_reply_address', 'my_gdpr_do_not_reply_address', 99 );

Now I can receive emails !!!

Last think, my email plugin is Mail Bank.

Also experiencing mail issues. I’ve tried to test the user tools but nothing is going through and no requests are being found with the GDPR tools on the WordPress admin area. I’ve tried turning off the STMP plugin I am using, but this has had no positive affect.
